Neuroendocrine Carcinoma (NEC) Overview

Neuroendocrine carcinoma (NEC) is a highly aggressive, poorly differentiated neoplasm characterized by rapid proliferation and early systemic metastasis. Distinct from well-differentiated neuroendocrine tumors, pulmonary and extrapulmonary NECs—comprising small and large cell variants—exhibit high proliferative indices (Ki-67 greater than 20%, frequently exceeding 55%). Driven by concurrent TP53 and RB1 inactivation, diagnosis requires urgent biopsy with immunohistochemistry verifying synaptophysin and the highly specific marker INSM1. The management paradigm is heavily dependent on anatomical origin. For high-grade pulmonary NECs, the standard combines a platinum-based chemotherapy doublet (etoposide with cisplatin or carboplatin) alongside frontline immune checkpoint inhibition via atezolizumab or durvalumab. Conversely, for extrapulmonary NECs, adding immunotherapy has failed to demonstrate a survival benefit, leaving platinum-etoposide as the chemotherapy-alone frontline standard. While the prognosis remains deeply guarded, salvage options are expanding through precision medicine. The delta-like ligand 3 (DLL3)-directed bispecific T-cell engager tarlatamab has delivered unprecedented responses in refractory settings; though its formal regulatory approval is restricted to small cell lung cancer, it serves as a critical off-label or clinical trial therapeutic target for DLL3-expressing extrapulmonary carcinomas. Urgent multi-disciplinary coordination is mandatory.
